THE DURA COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO WINDOW REGULATOR Application filed'october 3, 1924. Serial No. 741,466.

The invention relates to window regulators and is particularly applicable to mechanisms for raising and lowering windows of vehicles. One of the objects of the invention 5 is the provision of an improved window regulator of the quick acting type. Another object is the provision of an improved window regulator which'is locatediat a readily accessible andc'onvenient'point and in which the handle provides a considerable leverage in raising or lowering the window. A further object is the provision of an improved window regulator in which thehandle is movable in transverse directions to effect the unlocking and the raising or lowering of the window.

With these as well as other objects in view, the invention resides in' the novel features of construction and ;-combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings: r

. Figure 1 is an interior j side elevation, partly broken away, of a vehicle door having applied thereto a window regulator embodying my invention;

Figures 2, 3 and 4 are cross sections respectively on the lines 2-2, 33 and 4-,4 of Figure 1;

Figures 5 and 6 are side and end elevations respectively of the latch member.

In the present instance I have shown my invention as applied to the door 1 of a motor vehiclehaving the opening 2 in its upper portion and the chamber 3 in its lower portion. 4 is the window or closure for the opening 2 vertically slidable in the side uprights of the door from a position closing the opening 2 into the chamber 3. 5 is the lock board of the door extending between and secured to the side uprights thereof at the lower edge of the opening.

My improved window regulator is particularly applicable for raising and lowering the window beside the driver of a motor vehicle and is so located upon the door 1 that it is readily accessible and conveniently operated. As shown 6 is the mounting plate preferably in the form of a gusset plate, which is secured at its upper edge to the inner side of the lower edge of the lock board and at its front edge to the inner side of the front upright of the door,the drivers seat being adjacent to the rear upright of the door. This mounting plate has the outturned arc-shaped portion 7 below the lock board and extending adjacent to the front upright and the sector-shaped portion. 8 connecting into the outer edge of the arc-shaped portion 7. 9 is the arc-shaped rack having the series of teeth 10 upon its inner edge and 11 is the arc-shaped guard which will be subsequently referred to. The rack is secured to the inner side of the sector-shaped portion 8 adjacent to the arc-shaped portion 7 by suitable means such as the rivets 12,

which latter also secure the guard 11 to the inner side of the rack. With this arrangement the door is reinforced.

13 is the pivotal lifter arm journaled near o."

its inner end upon the pin 14 and suitably connected at its outer end to the window 4, as by means of the roller 15 which is secured to the arm and engages-in the channel 16 secured to and depending from the window.

The pin 14 is secured to the apex of the sector-shaped portion 8 and extends inwardly therefrom. The inner end of the lifter arm is extended beyond the pin 14 to provide the securing portion 17 for one end of the window counterbalancing spring 18, the other is loosely journaled upon the pin 14 to permit of rocking the lifter arm parallel to the axis of the pin and more particularly about the longitudinal axis of the lifter arm where by the latch member may be rocked to disengage its teeth from the teeth of the rack. The lifter arm and also the latch member are normally maintained at right angles to the pin by the coil spring 21 which surrounds the inner portion of the pin and abuts the lifter arm and the annular outwardly turned flange 22 upon the inner end of the pin.

23 is the handle for actuating the latch member to disengage the same from the rack and also for actuating the lifter arm to raise or lower the window. This handle extends at an angle to both the latch member and litter arm and is preferably located in the angle between the same. This handle is threaded at its inner end into the stub shaft 2 1 which is secured to the lifter arm 13 and latch member 19. As shown the stub shaft hasthe' oppositely extending foot flanges 26 upon the latch member and through both of which suitable securing means, such asthe rivets 27, extend for securing the stub shaft and latch member rigidly to the lifter arm. The handle has at its outer end the ball 28 atfording a grip and the relative lengths of the handle and litter arm are such that the han- V dle provides the necessary leverage for easy raising and lowering of the window. The parts are so arranged that the ball of the lifter arm in the closed position of the window is adjacent to the front upright of the door and in the open position of the window is to the rear of the pivot and nearly horizontal therewith.

To adjust the window the handle 23 is laterally adjusted inwardly thereby rocking the lifter arm 13 about its longitudinal axis and disengaging the teeth 20 of the latch member 19 from the teeth 10 of the rack 9 As shown particularly in Figure 6 the teeth of the latch member are offset to extend at an angle to the body of the latch member in order to facilitate the disengagement of these teeth from the rack teeth. The handle is then swung in the transverse plane about the pin 14 thereby swinging the lifter arm 13. Nhen the window has been adjusted to the desired position the handle is released and the spring 21 operates to re-engage the teeth of the latch member with the teeth of the rack to thereby hold the window in its adjusted position.

The arc-shaped guard 11 upon the inner side of the rack 9 has the inwardly offset inner edge 29 which is engageable with the outer end of the latch member 19 to limit 'the rocking of the latch member from locking position.

30 is the trimming at the inner side of the door and concealing the lifter arm, latch member, and associated parts, the stub shaft 24 extending through this trimming. 31 is the esc-utcheon surrounding the stub shaft and covering the portion of the trimming adj acent thereto. This escutcheon has the transverse tongues 32 engageable around the stub shaft and provided at their outer edges with the axially inturned project-ions 33 which are detachably engageable in the annular groove 34 formed in the stub shaft. lVith this arrangement of escutcheon the same may be readily applied.
